Amid an explosion of "jun'ai" -- or pure love -- television programs and books in Japan, movie companies are also getting into the act.

"Sekai no Chushin de, Ai o Sakebu" ("Crying out for Love, From the Center of the World"), directed by Isao Yukisada and produced by Minami Ichikawa and Kei Haruna, was released in May and became a blockbuster.

"Sekachu," as the teen love story is known, earned 8.35 billion yen and has been seen by about 6.25 million people.
